Hi I am running kernel 2.4.13 with ext3 support on an embedded system with 64 MB Flash and the .journal file takes size as 4 MB. Is it possible to minimize the .journal file ? With best regards/ Med venlig hilsen John Nørgaard

So if you format your filesystem with "mke2fs -b 1024" you can make the file be 1MB minimum by "tune2fs -j -J size=1" _____________________________________________________ | Martin Eriksson <nitrax@giron.wox.org> | MSc CSE student, department of Computing Science | Umeå University, Sweden

For flash, jffs2 might well be a more appropriate filesystem. Cheers, Stephen
